SPECIFIICATION forming part of Letters Patent No'. 398,042, datedFebruary 19, 1889.

Application tiled January 20, 1888. Serial No. 261,349. (No model) To@ZZ whom t may concern:

Be it known that I, HENRY H. HARRSON, of the city, county, and State ofNew York, have invented a new and Improved Printing-Ma' chine, of whichthe following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a front elevation of my new and improved printing-machine.Fig. 2 is a side elevation of the same. Fig. 3 is a central sectionalelevation taken on the line a: of Fig. 1. Fig. 4 is a broken detailedview of the paper-roll and spring-holder for the same.l

naled the roller C, of wood, hard rubber, metal, y

or other suitable material. Above the roller O is the type-roller D, inthe tace of which is secured the type D', preferably executed insoft-rubber sheets. The gudgeons CZ of the type-roller D are held inopen bearings d', made in the standards A A' which open bearingscommunicate with diagonal slots (Z2 in said standards, so that the saidroller may be readily removed from said standards and replaced forremoving or changing the type D', as circumstances require. Bearing uponthe gudgeons (Z are the curved springs cl3, which press the type-rollerdown upon the lower roller, C, and the paper E. One end of each springd3 is secured upon a fixed step, d', bya screw, d5, and the spring iscurved at d to fit upon the gudgeon, and its opposite end, d?, is curvedback to a horizontal position above the gudgeon, and upon this end actsthe adj usting-screw d8, held in a lug, d, and by which the pressure ofthe spring upon the gudgeon may be regulated to regulate the pressure ofthe printing-wheel upon the pa per. By removing the screws d8 thesprings d3 may be swung to one side ott from the gudgeons d, and theprinting-roller removed from the machine through the diagonal slots cl2,as will be clearly understood from Fig. 2.

The paper E is wound in a continuous ribbon upon a drum, F, held torevolve between two Corresponding rearwardly projecting arms, F' F', ofthe side standards, A A'.' From this drum the paper passes between therollers O D, which are revolved intermittently for drawing the paperalong and printing the same with an impression from the type D', onecomplete impression being formed for each complete revolution of thetype-roller D. G G' are the cutters or shears for cutting the paper E asit issues from between the rollers O D. The cutter G' is stationary, andits sharpv edge is on a line with the point of contact of the rollers CD, and a gnide-plate, G2, is held above it for guiding the paper overthe cutter G'. The cutter G is like the blade of a pair of shears, andis pivoted at a, and is formed with an extension, a', to which thesprings H H' are attached, which are attached also to the post I, risingfrom the base B at one side of the cutter G, and which springs serve tonormally hold the blade elevated, as shown in Fig. l, and permit it tobe closed by the lever J for cutting the sheets of paper.

The lever J and the rollers C D act in a certain relation to each otheras to time, and are all operated from the same crank-shaft, K, throughthe mediumot" a mutilated gear-wheel,

L, formed with a cam, L', secured upon the said crank. The mutilatedgear L meshes with the pinion M on the gudgeon b of the roller O andcommunicates intermittent motion thereto, and the roller O is gearedtothe type-roller D by gear-wheels N N', so that the roller Ocommunicates intermittent motion to the sai d type-roller. The lever Jis fnlcrnmed upon the gudgeon b, as shown in Fig. 2, and at one endreaches under the extension a' of the blade G, and at the other endreaches under the shaft K, so that t-he cam L will depress the said endof the said lever and correspondingly elevate the opposite end of saidIOO (l l) are at rest, and the blade (l remains at s This to the teltljand applied through the rollers rcstwhilc the rollers C l) are inoperation, so

that b v a single revolution ol' the crank K the rollers (l l) will. bcrevolved a complete revolution, inkingl thctw'peD' and printing a stripP O to the type on the roller l). Alf'pon the hollow gudgeon 7.1 securedthe pointer in", which acts between the. small lugs m m at thc end ofthe outer tuhe/`, which lugs act as stops to the pointer und prevent theinner tube 'from beingI turned too l'ar in either di l rection, and thepointer serves also as an Aindicator to assist in registering the holes`in ol' the paper li, and the blade G closed and rel' turned, thusellccting the cutting ott' ol the printed portion oli' the paper.

The type is inked bythe two inking-rollers O P and the tubularink-reservoir Q.

The giuflgeons c oli' the roller O are held in open bearings c in thestandards A A', and

said roller is held in contact Awith the roller I l) by a coiled spring,O', at cach end. The lower end ot" each of these springs is made fast toa lugl on the standard, while to its upper end is secured a ring, c2,which slips loosely upon the gudgcon c. These rings or sleeves may be@asiliremoved from the said gudgeons, thus ('letaching the springs fromthe roller @,which, owing to the open bearings c, may be readily removedand replaced, which necessary to remove and replace the typeroller lf).

The giu'lgeonsf olf the upper inking-roller are likewise held in openbearingsf", formed in the end pieces, l R, which are pivoted at /t tothe standards A A', and on each of the gndgeons is placed a loose ring,f2, to which is attached the upper end o'l a coiled spring,

I, the lower end ol? which is made fast to the standards. lv slimiingthe rings f2 oft' from the gudgeonsfthe wheel P may be lifted out ot'the hearingsj". lfor holding the roller P in contact: with the roller O,the end pieces, R R", iurn on pivots 7i lor that purpose, and owing tothese pivots the roller lf may be pushed bach awa)` from the roller()when the same is to be removed from its bearings. The ink-reservoir (.2is join-nailed in the said end pieces, Vit' l{,and in a trough, lt,which serves to catch an)r drip ot' ink.

The reservoir is inade oll twotubesM/'P/Q one placed within the other.The outer tube,j, is l'orincd with a seriesoi' holes, j?, and the innerwith a correspoinling series' ot' holes,j3, and around the outercylinder is placed a lelthj". The outer tubc,j, is open at one end andt'ornwd with the annular liange 'i at the opposite end. The inner tube,j", is formed with a giu'lgeim, 7.', at one end and with a hollowgiulgeon, li", at the other, which passes through the openingl 1T in theend ot' theouter tubehj. lhe inner tube, 1j', is lilled with ink throughthis hollow gudgeon lt", and is closed b v a plug, 7:?, which t'orms oneof the journals for the hiking-roller. liv turning the inner tube sothat its holes'ji do not register with the holes/"f ol' the outer tubethe [low ol inl; will be stopped, but by tu rn i ng the inner tube tobring` its holes into registration with the holes ol the outer tube inl:will be supplied the two tubes.

The drum l?, on which the paper E is wound, is composed of the enddisks, p p, and the core F2, to one end oil which the disk p :isattached. One end of the core Fi is recessed, as shown at q, to receivethe head oi the rod. F3, held in a sleeve, F4, attached to the arm F ofthe standard A. The rod F3 is provided with the small rod F5, whichpasses through the said arm F', and in the sleeve Fll is placed thecoiled spring F, which constantly presses the rod F3 into the recess q,thus holding that end of the drum, the opposite end being held by astud, s, attached to the opposite arm, F', of the standard A. The diskpis attached to the'rod F3, as shown in Fig. 4, and said disk is providedwith a rod, t, by which the said disk and rod may be conven iently drawnto the position shown in dotted lines in ligx 4f, for releasing the coreF2 and for receiving another core fitted with paper.

The roller C is prevented from turning back b v a spring-pawl, S, whichengages with. the teeth of the gear-whecl N, as shown clearly in Fig. 7,and the type roller is prevented from turnin g too i'ar by hand or bymomentum by the pawl T7 formed with the arm u and toe u', which latterengages with a toe, u, on. the hub of the pinion M. lhe arm u projectsin the path oi the cam L and is struck. thereby, so that the cam at theproper time lifts the pawl T out ol engagement with the projection u?and releases the parts. To cause the pawl T to drop suddenly at'ter thecani L has passed the arm u, l form said pawl with the extension r andconnect to this the lower end of the spring` i", which is connected atits upper end to the standard, so that the spring exerts a constanttension upon the pawl.

Having thus described my invention, what l claim as new, and desire tosecure by Letters p Patent, is-

l. In a printing-machine, the standards A A, having the open bearin dand diagonal slots di, reaching to the same, in combination with thetype-roller D, lower roller, C, gudgeons d, springs d3, pivoted to thestandards and arranged. to rest upon. the gudgeons d, and thc screws di,held in studs attached to the standards and adapted io hold the springs(Z3, substantiall)T as described.
